IPOLISHING CLOTH.

Application filed July 16, 1927.

This iureution relates to devices for cleaning, polishing and renewingthe surfaces of finished articles, and more particularly to manuallyoperated friction devices of soft and pliable nature, capable ofconforming to the shape of the article to be polished.

Such devices are commonly in the form of a cloth, used as a duster, orby dipping in a solution of soapy or pasty material, including 1.0 anabrasive, may be applied and due to their rubbing effect, producedesired results.

Others have incorporated steel wool and like sharp cutting elements toabrade the surface and by mechanical action. level and smooth the samebut incidentally cause scratches not desirable on a finished surface.

It is one object of the present invention to provide a cloth of softopen texture in which the interstices between the strands are filledwith a polishing material, causing it to adhere, beside completelyimpregnating the woven threads so that a durable and efficient device isproduced.

A further feature is in the provision of a polishing cloth adapted foruse by merely moistening the same and which is entirely free from cangerof scratching or marring the surface to which it may be applied.

These and other objects, such as economy in both construction andapplication, convenience and attainment of purpose, are secured by thenovel construction and process hereinafter described and shown in theaccompanying drawing, forming a material part of this disclosure, and inwhich Figure l is a plan view of a polishing cloth made in accordancewith the invention, one corner being unthrcaded.

Figure 2 is a magnified cross sectional view of a fragment of the same.

The threads of the fabric, both warp 5 and filling (3 are preferably ofloosely twisted lilii Serial No. 206,176.

These powders are mixed in a solution known as lemon oil, consisting ofacetone, benzine and a little pyroxylin, which with a small quantity ofamyl acetate gives it a characteristic odor.

To this compound may be added a suitable adhesive such for instance asrosin, litharge or wax and the whole agitated vigorously while the clothis immersed and caused to take up i the greatest quantity possible andthen dried, more than one saturation treatment being given if desired.

Thus the fibers constituting the fabric are impregnated as well as thespaces between adjacent threads, and after the final treatment thecloth, when in a moist condition, is passed between rolls, furtheraflixing the minute particles to the fabric.

These cloths, which may be of any convenient size, may be then dried,folded and placed in suitable containers ready for use.

In applying the cloths, they are moistened with water and used by handwith such friction as may be regarded necessary, leaving a line whiteprecipitate that upon becoming cry is removed by a plain cloth or thelike, leaving a finely polished surface on finished metals, varnishedand lacquered objects such as are commonly encountered.

Although the foregoing is descriptive of the preferred embodiment of theinvention, it will be apparent that minor changes may be made in itsconstruction, without the exercise of invention or conflicting with thescope of the claims hereto appended.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A polishing cloth consisting of cotton fabric made of soft twistedyarns loosely woven, a composition of mild abrading powders of whichwhiting predominates incorporated by pressure in the weave and in thefibers, and rosin in a finely pulverized condition to act an adhesive toretain the pew: ders therein.

2. A polishing cloth consisting of a loosely woven cotton fabric, and anaqueous solution of acetone, whiting and an adhesive forced into thefibers and weave of said fabric.

In testimony whereof I alfix my signature.
